Pullet constipated/egg-bound?

[murphynhazel12]

One of my 20 week old pullets (who has not laid yet) has started to constantly be in "pushing out an egg" pose and I'm worried that maybe she has a blockage or she can't fit an egg out through her teeny body. She doesn't seem lethargic and is eating/drinking fine, but it's bizarre to see her pushing even as she's eating worms outside. I did see some poop (normal looking) come out earlier when she was pushing, however. She kept doing it even after the poop came out though. What do you think this is?

She may be getting ready to lay. I would just keep a close eye on her, unless something else happens and she looks ill. Sometimes they "practice" for a bit before they lay, usually by sitting in nest boxes. And sometimes they don't really quite know what's going on at first. If birds get egg bound they usually cannot poop and they will appear very ill. If she's behaving normally otherwise, I'd just keep a close eye on her.
